Counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. Technical Features Counterbalance valves should be set at least 1.3 times the maximum load induced pressure. Turn adjustment clockwise to decrease setting and release load.
